kinetic energy because the bird is in motion
Aswer:
False, the values of the distance traveled and the displacement only coincide when the trayectorie is a straight line. Otherwise, the distance will always be greater than the offset.
Although these terms are used synonymously in other cases, they are totally different. Since the distance that a mobile travels is the equivalent of the length of its trajectory. Whereas, the displacement will be a vector magnitude.

Answer:
2.8351×10^7 N/kg
Explanation:
We know that,
W = mg -------(1)
where W = weight, m = mass, g = gravitational acceleration
Also from Newton's law of gravitation we know that,
F = GMm/r²
Where,
F = gravitational force,
G = universal gravitational constant
M,m = masses of object under gravitational influence
r = distance between the two center of masses.
Here we get
F = (Gm/r²)M -------(2)
From 1 and 2
The acceleration due to gravity = gravitational field intensity
So if you consider the gravitational field intensity at the surface of the asteroid,it is equal to the acceleration due to gravity at the same place.
So we get,
g = (6.67×10^-11)×9.3835×10^20/(47²) = 2.8351×10^7 N/kg
